PATENT Qrrronc IMPROVEMENT IN lNVALlD-BEDSTEADS.

Specification forming part of Letters Patent No. 168,503, dated October5, 1875; application filed July 24, 1875.

To all whom it may concern Be it known that I, ABRAHAM KAUFFMAN, ofAnnville, in the county of Lebanon and State of Pennsylvania, haveinvented a new and valuable Improvement in Invalid -Bedsteads and I dohereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the annexed drawings, making a part of this specification,and to the letters and figures of reference marked thereon.

Figures 1 and 2 of the drawings are representations of side elevationsof my bedstead, and Fig. 3 is a longitudinal vertical sectional view ofthe same. Fig. 4 is a transverse vertical sectional view thereof.

This invention has relation to invalid-bedsteads and it consists in theconstruction and novel arrangement of the inner adjustable head and footframes, with their windingshafts, pawls and ratchets, the cords andpulleys, and the suspended reclining frame, adapted for attachment toordinary bedsteads of varying lengths, where the foot-board is made lowin the common fashion, as hereinafter shown and described.

In the accompanying drawings, the letter A designates the frame of anordinary bedstead,B the head-board and O the foot thereof. D D representthe four posts or standards forming end frames D D These are designed tostand within the bed frame, as shown, being secured thereto by suitableclips E. At or near their lower ends the supports D are connected bytie-braces F. G G indicate the winding-shafts, journaled in suitablebearings a, attached to the posts D and pro- Vided with the pulleys Hand ratchets K. L indicates the pawls, which engage with the ratchets.These are pivoted to the ends of arms M, which are secured to the postsD and extend along the inside of the side rail of the bedstead for acertain distance, and then under the same transversely, and upward onthe outside of said rail to the pivots of the pawls, which extend in thereverse direction to the ratchets. At the ends of the winding shaftskey-seats b are made for the attachment of the operating cranks N. Srepresents the stretcher, consisting of a rectangular frame, S, to whichis secured the web upon which the patient rests. Cords c are passedthrough perforations in the frame, and extend upward over pulleys dseated in bearings in the tops of posts D, and thence downward to thepulleys H of the winding-shafts, to which they are secured.

At the foot of the stretcher-frame the side rails m are perforated, asindicated at z, for the attachment of the cord at different points. Thisend of the stretcher is thus enabled to be extended beyond the foot of ashort bedstead, the head and foot frames D D being moved toward eachother sufficiently to fit within the frame of such bedstead, as aboveset forth.

The stretcher is laid with the webbing upon the bed or mattrass, and theframe well over the edge. The patient, being placed upon the Webbing, israised, when necessary, clear of the mattress, by winding the cords 0upon the pulleys H, the keepers or pawls L and ratchets K serving tohold the stretcher, when raised, at any height required.

What I claim as new, and desire to secure by Letters Patent, is-

1. An invalid-bedstead attachment, consisting of the head-frame D theadjustable footframe D and the suspensible stretcher-frame S, having adjustin g-perforations Z for the suspendingcords c, substantially asspecified.

2. The combination, with the stretcher S and its suspending-cords c, ofthe head and foot supports D D having the windingshafts G, pulleys H andd, pawl-arms M, pawls L, and the braces F, connecting the feet of saidsupports, substantially as specified.

In testimony that I claim the above Ihave hereunto subscribed my name inthe presence of two witnesses.

ABRAHAM KAUFFMAN.
